IMPROVED CHEESE-PRESS.

TO ALL WIjIOM IT MAY OONCERN: Y

Be it known that I, JACOB ERDLE, of South Bristol, in the county ofOntario, and State of New 4York,l1ave invented a certain new and usefulImprovement in Cheese-Tresses;` and I do hereby declare that thefollowing is afull and exact description thereof, reference being had tothe accompanying drawings, making part of this specification, in which-The figure represents a central vertical s ection ofthe machine.

Myimprovement'consists lof the combination of the weighted lever and thescrew, whereby an even and uniform pressure is produced, and which arecapable of adjustment without removing the pressure, the whole beingarranged andoper-ating substantially as hereinafter set-forth. 4

t In the accompanying drawing, A indicates the bed-plate, restingstationary on legspp; B, the curb, and C the follower, which is presseddown by the combined action of screw D, that turns in a nut in cross-barE, and the weighted'lever, as will presently he described.

'Io the opposite ends of cross-baril are connected perpendicular rods aa, that `extend. down Vthrough hollow standards, b b, and connect attheir lower ends to cross-'bar F. Extending ldown on opposite sides ofthe bedplate A are fixed bearings, c c,rin which rest the ends of theshaftGr, the shaft being provided with a crankbearing, el, that isjointed to lever e of cross-har F. On one end of shaft Gris secured alever, H, having a weight, I, attached. c

By turningdown the screw D, the cross-bar E, not being stationary, willrise up on the threads of the screw, and consequently draw-up theconnecting parts, and elevate the lever II. Then, by means oftheweighted lever, a steady and uniform pressure is produced,therebydraw-ing` down upon the adjustable-parts until the ends ofcross-bar E rest on top of the hollow standards b b, and prevent furtherpressure, when the screw D is again turned down, and the operationrepeated as before. This isall accomplished without at any time removingthe pressure from the follower. p

By simply inserting blocks (shown in'red lines) between the cross-bar Fand bed-plate A, the parts may be held stationary, and the pressoperated by the Vscrew alone. i l y I amaware that presses have beforebeen patented, in which a weighted lever has been used to produce acontinuous pressure, without relieving the pressure iu readjustng, butsuch devices are much more complicated and expensive than mine, and muchmore liable to get out of order;A In my device the arrangement is verysimple and cheap, and the operation performed with as little diculty asin ordinary presses, where screws alone are used. By simply turning downon the screw, the adjustable parts'are plaeedin position tov produce acontinuous pressure, and still allow it to settle without overcomingthestrain. v

In contradistincton to such-arrangements-as above indicated, I combinethe two siniplest and most eicc'tive mechanical powers, viz, the-screwand weight, lto readjust and continuodsly .apply the pressure, thisbeing accomplished simply hy the square connection E-F, a a. l i

What I claim as my invention, and desire to secure by Letters Patent,isV

The arrangement and combination of' the screw D, cross-bars E F, rods aa, crankfshaft/ Gr, and weighted lever II, operating substantially asand for the purpose set forth.

In witness whereof, I have hereunto signed my name, in the'presence oftwo subscribing witnesses.
